One or more beam edge topologies could not be shared. This can occur if the beams associated with the shared edge have non-matching properties. Beam properties like the section definition, offset and the “IsReversed” flag must match.

What this warning means?

[Ashish Khemka]

For edge-to-edge connection can you try a bonded contact with the MPC algorithm?

Hello Ashish

My assembly is beam shell assembly.

I used bonded contact between beam and shell

Also

Bonded contact between beam to beam.

But Iam still getting this error.

Also I don't know what can be reason when shared topology don't work for model which contains beam?

If I force share option over beam in beam shell assembly under Spaceclaim,than under mechanical, my beam get disoriented and some don't show up there... How solve this issue?

[Ashish Khemka]

According to the warning message, share topology may fail as the reverse flag was inconsistent. Try setting it both to false and share topology should work.

Hello Ashish

I did all Reverse flag to "False"..Still i am getting same warning....What to do..thanks..And also after doing all 100 beams, "False", all beams are in opposite directions of each other in spaceclaim.

[tumulpurwar]

Probably i extracted those solid beams in to beams in intial stage in wrong way(i guess wrong orientation),thats why neighboring beams get different orientation if i set them all to "False".

So i believe, Extraction tool of spaceclaim for beam is Orientation sensitive?Can you please say Yes or No?

Hi ashish
I have error below
I have one error coming
ERROR: Unable to view geometry. Unable to get model.



I was performing a static structural simulation in ANSYS 2019R3. I meshed geometry, applied loads and boundary conditions and solved it. After about 5 seconds, ANSYS Mechanical automatically shuts down itself leaving behind the project schematic window.

I don't know how to resolve this. Please help me out as soon as possible!

It looks like the project is corrupted. You can try restoring the project. Please follow the steps below:
==========================================================================================
In your project folder, there should be a SYS.mechdb file for each Analysis object that was on the schematic.
Make a copy of SYS.mechdb to another folder
Rename the copy to SYS.mechdat
Create a new Project.
Go to File > Import
Change the extension filter to .MECHDAT
Browse to the SYS.mechdat and open.
...do this for each .mechdb you have and the analysis system you want to restore.
Save the project to a new name/folder when you are done.
==============================================================================================

Thanks Ashish for the answer.

Hi Ashish

For local vibration analysis, when local structures are in contact with fluid, the added mass effect of the
fluid must be considered in the calculation. The added mass can be considered either through virtual mass
method using boundary element method (BEM) such as ÔÇÿMFLUIDÔÇÖ card of MSC NASTRAN or using
empirical formulas.
How to get added mass from Ansys?
